ENGINE-STARTING DEVICE.

Specification of Letters Patent Patented June at, 1911.

Application filed July 20. 1910. Serial No. 572,876.

To all whom it may concern:

Be it known that. we, CHARLES M. BURTON and R10 GARDNER, citizens of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Engine-Starting Devices, 'of' which the following is a specification.

The object of this invention is to provide a comparatively simple and eificient form of starting mechanism for explosive engines, one which is especially adapted to be used on automobiles or the like.

The invention eliminates the necessity of having to crank the ordinary explosive motor in the starting of the same, and an extremely compact and desirable arrangement of parts is embodied in the construction.

' For a full understanding. of the invention reference is to be had to the following detail description and the accompanying drawings, in which- Figure 1 is a side elevationof the mecha-.

nism showing the preferredembodiment of the invention; Fig. 2 is a top plan view; Fig. 3 is a fragmentaryview of the auxiliary motor having a side portion broken away, and Fig. 4 is a fragmentary View showing more clearly the means connecting the lever with the swiveled bracket.

Specifically describing the invention, in the drawings 1 denotes a drivewheel such as the fly wheel of the engine shaft, said fly wheel being of the ordinary type, constructed, however, with a bevel gear 2 at one side thereof. .Meshing with the gear 2 is a pinion 3 carried by a short shaft 4 mounted in a suitable bearing carried by a swivel bracket 5. The pinion 3 is located at one end of the shaft 1 while supported on the opposite end of the shaft for rotation therewith is the rotary piston 6 of an auxiliary motor comprising the casing 7 inclosing said piston 6. A suitable lever 8 is mounted upon arock shaft 9 the latter having an arm 10 connected by a link 11 with the base of the swivel bracket 5. By operation of the lever 8 the bracket 5 may be turned so as to throw the pinion 3 into and out of engagement with respect to the gear 2. An air compressor is provided in the form of a cylinder 12' having trunnions 13 supported by pillow-blocks 14 on a suitable base 15, permitting the cylinder 12 to rock when its piston 16 is recip. rocated therein by means of the connection between the piston rod 17 and a friction wheel 19. The friction wheel 19 is mounted .upon the upper end of the piston rod 18,

remain in frictional contact with the fly wheel 1. A suitable air reservoir 23 is con nected by the main pipe 24, and branch pipes 25, with the cylinder 12, the latter having suction valves 26 at opposite ends. The air from the reservoir is caused to pass therefrom to the auxiliary motor 6 through the pipe-27, and'when the valve 28 in the length of the pipe 27 is opened, the pipe 29 connects the reservoir 23 with the lower ends of the cylinder 21 said arrangement of parts permitting of the following operation: Should it be desired to start the engine having the main shaft A on which the fly wheel 1 is mounted, the operator actuates the lever 8 so as to throw the pinion 3 into engagement with the gear 2. The valve 28 is then .opened permitting air under pressure to permitting the piston 20 to move down Wardly until the wheel 19 is in contact with the fly wheel 1, whereupon the wheel 19 will be rotated operating the piston of the compressor 12 so as to supply additional air under pressure to the reservoir 23. When the pressure in the reservoir 23 becomes increased to the desired maximum said pressure will raise the piston 20 and also the wheel 19. When the wheel 19 is moved from contact with the fly wheel 1 the compressor 12 stops.

It is contemplated that the pipe 27 will have flexible action at 2'1 with respect to the auxiliary motor, and after the main engine has been started, the lever 8 will be operated to disengage the pinion 3 from the gear 2.

Having thus described our invention, what is claimed as new is:

In an engine starting device, the combina-- tion of a drive wheel provided with a bevel gear at one side thereof for rotation there- "with, a shaft, a pinion on one end of said shaft, a swiveled bracket having a bearing in which said shaft is mounted, a motor comprising a casing and piston and mounted onthe other end of said shaft, a prwsure reservoir, piping connecting the reservoir with the motor casing to su ply a pressure medium to the latter and inc uding a flexible portion permitting movement'of the motor, and a lever operably connected with the swiveled bracket to move the latter into pos'itions in which the pinion on said shaft will be engaged or disengaged with respect to the gear on the drive wheel.

In testimony whereof We aflix our signa- 15 tures in presence of two witnesses.
